Use of mechano lattice analysis in prediction of pavement performance

摘要: The mechano lattice model utilises elastoplastic behaviour rather than the elastic utilised by other analysis methods. requires young's modulus and poisson's ratio of material, together with data derived from repeated loading laboratory prepared specimens. is three dimensional involves a sequential technique simulating one directional rolling 1500 to 2000 computation cycles converge. A total 32 load deflection histories are followed for each 1980 units. This paper discusses several studies in Australia, South Africa United States which has been used. range pavements modelled includes asphaltic concrete, granular, test track type pavements. In all these found be fairly reliable predictor pavement performance (a).
